Pear3DEngine is a modern and modular 3D development framework that lets you create professional games, simulations and more. You are free to develop your program in C++, XML or LUA and publish it as open source software or selling it as a commercial program. The rendering engine uses internally OpenGL or DirectX optionally. The planned editor supports software development on Linux, Windows and maybe MacOS X. DirectX 9 and Windows XP are not supported and support is not planned in the future. One goal of the Pear3DEngine Framework is to use the latest and most promising algorithms and techniques from the 3D and IT scene.

This is the description of the engine that you can find on SourceForge. But why a new engine? Are there not enough in the world?
